LOCK.

SPEIFICATION forming part of Letters Patent No. 294,901, dated March 11, 1884.

Application filed August 20, 18H3. (Model.)

To LLZZ whom, it may concern,.- Y

Be it known that I, DAvInMoRRIs, of Log Cabin, in the county of Morgan and State of v Ohio, have invented a new and Improved Lock, of which the following is afull, clear,

and exact description.

rIhe object of the invention is to improve that class of locks in which a slide-bolt is moved in either direction by a wiper, as hereinafter described. l

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate cor.- responding parts in all the iigures.

Figure l is a sectional elevation of the case of the lock and part of the mechanism, showing the bolt in side elevation and thrust forward into the catch. Fig. 2 is asimilar section of the lock, taken in a plane at right angles to that of Fig. 1. It also represents'a portion of the key. Fig. 3 is a section inthe same plane as Fig.` l, the bolt being drawn back or down out of the catch; and Fig. 4L is a perspective viewof the wiperemployed for throwing the bolt by the key, also for locking the bolt.

The bolt a is preferably a plain cylindrical rod for most of its length, and is fitted to a case, b, of similar form and' proper size to receive the bolt, this form being preferred because of being theV simplest to construct, and also to t inthe door or other objett to which the lock is to be applied 5 but I may-of course construct the bolt and casein any other form of cross-section.

Inside of the case, and preferably at theinner end of the bolt, and for a suitable distance therefrom along the bolt, I cut away the sides of the bolt, or otherwise construct the boltto'form the flat section c, in which I make a deep and wide notch, e, wherein the wiper f works to throw and lock the bolt, said wiper being provided with the pivot and key studs g, by whichit is mounted on the wiper-stand h for supportsaid stand consisting of a base, by which itis attached to the inner end of the lock-case, and two upright or horizontal arms. f according as the lock or open side of the notch, between the ends t' and j of said notch. At each end of the notch .there is a spring, k, against which the wiper acts to throw the bolt, the springs being to rise a little after the wiper passes and prevent it from being jarred out of its position, or turned out by any instrument except the key. There is an undercut ledge, Z, in

the end 1L of the notch, where the wiper rests when the bolt is shifted forward into the catch m, in which the wiper is returned by the incline of the ledges and by the gravity of the wiper, so that it efectually resists the opening of the lock by forcing the bolt back. rI'he ends of the pivot-studs g are squared for a socket-key, a, to be used for turning the wiper, the socket being formed in the end of a small rod., which makes asmaller and simpler deviceto carry inthe pocket than the ordinary door-keys.

The form of bolt and case which may be used in this improved lock enables the bolt to be tted nicely to the case throughout its whole length, and to be rmly supported thereby, which is a more permanent and bet# ter working arrangement thanis afforded `by clips, guides, and' other attachments to the interior of the case for the support of the bolt. t
